A while ago The Akria Project team ran an Indiegogo campaign, they hit their mark and this is the results.

The Akira Project is a crowd-sourced, non-profit project meant to create a live action fan trailer of AKIRA, the renowned manga-turned-anime film from the late 1980′s; a stunning example of both mediums as art forms. While Hollywood has been working on a live-action Akira movie for a few years now, we, as fans, wanted to take a shot at making our own adaptation. A chance to stick as close to the source material as possible. A chance to do Akira Justice.

We launched an Indiegogo campaign in July 2012 as part of a crowd sourcing effort to make this project come to life. Many people contributed not just financially but offered their time and talent to help the production that was shot in Montreal, Quebec from November 2-5th 2012. What started out as a simple idea between two guys having a beer (Hey! It'd be cool to see Kaneda ride his bike around Neo-Tokyo!), became a global endeavour, filled with adventures and hurdles, involving more than 40 artists in 12 different countries.

After a year and a half in post-production, we are proud to present the project to Akira fans the world over. We hope to have done justice to the timeless work of Katsuhiro Otomo and look forward to, someday, seeing the full scope of the Akira story translated to the big screen as a live-action.

If these guys had a massive Hollywood budget, just imagine what they could do!
